In this sculpture by artist Vincent Kohler, an exploded view of a tree shows various cuts of lumber and what parts of a tree they’re from. You may be surprised to discover that the piece is not made of wood, but rather resin and polystyrene. It’s as beautiful as it is educational.

    pretty cool.

    My great grandfather worked in a lumber yard. Family legend has it that he could tell how much would in board feet would come out of a tree just by looking at it.

    I was always skeptical. Now I see how that could work.

    The only thing missing is the pile of wood chips representing the parts taken off to square up all the lumber pieces, nothing goes to waste.
